The intention of this handbook is to provide a variety of inspiring Polish and foreign examples with regards to the principle of gender equality in projects co-financed by the European Social Fund. It presented good solutions addressed to both sexes .In the section devoted to Polish examples, the publication is based on the recommendations of members of the Working Group on Equal Opportunities for Women and Men (which supports the Managing Authority of OP HC), interviews with people implementing those projects, and the analysis of information available in the public space. The final selection of projects presented was influenced by a desire to show the greatest diversity in the area of project subjects: they are not, however, "good practices" in the classic sense, because some projects are still being implemented, but "an inspiration". These examples are intended to provide background material for those who are preparing projects. As for examples of projects in selected European countries, they show the areas in which the issue of equal opportunities for men and women both can be pursued at the national as well as local level. By presenting the most interesting "equality" solutions the Managing Authority of the Human Capital Program wants to encourage potential applicants to take this principle into account at every stage of the project while preparing applications for funding.
